What is it?
Step-by-step explanation:
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.
S / 13 = 2....multiply both sides by 13
s = 2 * 13
s = 26 <=
Answer:
Step-by-step explanation:
<u>Associative property of multiplication:</u>
It makes calculations easier by by grouping easy ones. Applying to given expression:
- 6(3/2 * 1/5) =
- (6*3/2)*(1/5) =
- 9*1/5 =
- 9/5
Answer:
Step-by-step explanation:
3.45/5=0.69
0.69x$125=86.25
0.75x$125=93.75
93.75-86.25=$7.5
Troy would get $7.50 more than he would have if the exchange rate had stayed at .69
